11 | ## Qt制作的一键式程序
12 | 
13 | 下载 https://github.com/baidut/GoHosts/releases
14 | 
15 | ![image](./ui.jpg)
16 | 
17 | ## 不想下载？访问在线hosts
18 | 
19 | 1. 访问[在线hosts](https://raw.githubusercontent.com/baidut/GoHosts/master/hosts.txt) 复制内容
20 | 1. 替换系统的hosts文件
21 | 
22 | hosts文件位置
23 | - Widonws系统 `系统盘:\windows\system32\drivers\etc\hosts`
24 | - Linux/MAC系统 `/etc/hosts`
25 | - Android系统 同Linux，需要ROOT
26 | 
27 | ## 【Windows】找系统hosts文件麻烦？
28 | 
29 | 1. 任意位置新建记事本，将下面的内容复制到记事本中
30 | 1. 把记事本后缀名改为bat
31 | 1. 以后以管理员账户打开该文件即可弹出系统hosts文件
32 | 
33 | ```bat
34 | notepad "%SystemRoot%\system32\drivers\etc\hosts"
35 | ipconfig /flushdns
36 | exit
37 | ```
38 | 
39 | ## 【Windows】右键管理员身份运行比较麻烦？
40 | 
41 | 1. 创建具有管理员权限的快捷方式，具体方法自行百度
42 | 1. 以后每次双击该快捷方式即可打开
43 | 
44 | ## 注
